Furthermore, the layered built-up and the according manufacturing processes of these materials give the possibility to integrate functional elements, like electronic components or piezoelectric sensor/actuator modules.
Thus, these innovative materials allow the development of a new generation of function-integrative lightweight structures with material-integrated structural health monitoring, energy harvesting, or active vibration damping functionalities [1-2].
∆Q=C1∙(U1-U2 ) (1) Thermoplastic materials and in particular the used polyamide 6 (PA6) show a high dependency of their dielectric properties according to temperature or humidity.
In this case, the elevated conductivity can be caused by filler materials in the thermoplastic matrix system.

Introduction Abrasive Flow Machining（AFM） is an innovative finishing and polishing operation with a gentle material removal mechanism.
In this way, the flow coefficient can reach up to 0.8 and the dispersion rate of flow can be controlled within ±2% if the material of workpiece is identical and the dispersion rate of flow is within ±5% before grinding.
It is because the grinding speed can not be adapted to the difference of material and aperture between different workpieces in time under constant pressure conditions.

Experimental Section Materials Materials used in this study include fly ash from PT Madukismo Factory, Yogyakarta, Indonesia.
Other materials include dithizone (1,5-diphenyltiocarbazone), Cadmium Iodide (CdI2), sodium hydroxide (NaOH), hydrochloric acid (HCl), ammonium hydroxide (NH4OH), potassium nitrate (KNO3), disodium ethylene tetraacetate (Na2EDTA), and distilled water.
The obtained material was then washed with distilled water to a neutral pH.
